noorme AND srnme ELEMENT Applicatio filed May 26,

This invention relates to improvements in roofing and siding elements and is a continuatlon in part of my Patent Number 1,759,901, dated May 27 1930.

,6 It is one of the objects of this invention to provide an improved roofing and siding ele ment having tabs which are constructed in a novel shape to provide .relatively wide sections for overlapping the nails extending 1 through an element below so as to amply.

cover the holes formed by said nails to prevent rain or moisture from working thereinto and to effectively cover and protect the abutting ends of two adjacent shingles in the course below.

A further object of this invention is to provide a roofing and siding element having tabs with relatively wide lower edges so' that when the elements are laid on a roof and are viewed of double thickness.

A-more specific object of this invention is to provide a roofing and siding element in which the tabs are of greater width at their lower edges than at the point where they join the body portion.

A further object of this invention is to provide a roofing and siding element which, when laid with other elements on the roof, will form a plurality of symmetrical figures to make a pleasing impression upon the eye. A further object of this invention is to provide a roofing and siding element which is simple in construction, which can be economically cut from a blank and which is well adapted for the purposes described.

With the above and other objects in view, the invention consists of the improved roofing and siding elements and its parts and edgewise there will be relatively long portions combinations as set forth in the claims and 1930. Serial in. 455,841.

Fig. 3 is a plan view of a group of said elements as they appear when assembled upon a roof.

Referring to the drawing the shingles are preferably formed from a sheet 5 of the usual 55 composition material. Said sheet is cut longitudinally along the line 6 to form alternating tabs and recesses of elements to be cut from each side of the sheet. The sheet is then cut transversely along lines 7 which ex- 00 tend inwardly from each side and only partially across the sheet. The lines 7 may be spaced any distance apart according to the number of units which it is desired to form in one strip.

The completed elemjent shown in Fig. 2 comprises a body portion 8 which is substantially rectangular in shape. The exact shape of the body, however, may be varied as desired. Said body portion has depending 70,

from its lower edge spaced apart tabs 9. The sides 10 of said tabs are diverging so that the lower edge 11 is of greater length than the upper edge of the tabs where they connect with the body. Between each pair of tabs, recesses 12 are formed, the said recesses being complementary in shape to the tabs.

In assembly the elements are laid one above another as shown in Fig. 3 with the lower edges 11 'of the tabs registering with the upper edges 12 of the recesses. Nails 13 are in serted near the lower edge of the body portion at points midway between two tabs and at points adjacent the ends of each element. Said last mentioned points are also substantially midway between two tabs when another element is placed in the same row. Said nails are covered over by the tabs of an element in the row above. By providing tabs with wide lower edges the nails are positioned farther away from the corners of the tabs than is the case in shingles where the tabs have converging sides to form narrow lower portions. Thus the nail holes are more thoroughly protected from rain and moisture working into the same and the abutting ends of two elements in the same course are eflec-, tively protected as at 14, the outwardly diverging sides of the tabs providing a greater width of coverage and serving to direct rain and the like away from the joint at the abutting ends. It is further to be noted that when a group of elements is viewed edgewise that there are long portions of double thickness formed by the lower edge of a tab and the edge of a recess. These portions of double thickness are rendered longer than usual due to the peculiar shape of the tabs. The finished roof will present a group of four-sided figures in which one pair of opposite sides is V-shaped, the apexes of said sides extending toward one another.

Although only one form of the invention has been shown and described, it is not desired to be limited to this exact showing, as the broad concept of the invention includes all changes and modifications as may fairly come within the scope of the claims.

What I claim is:

1. Shingle elements assembled on a roof in overlapping courses, each course having alternating depending tabs and recesses, the recesses being complementary in shape to the tabs, and each course comprising a plurality of separate elements having end extensions which abut one another, the lower edges of said abutting end extensions forming the bases of some of the recesses, said tabs having their lower edges of greater length than the upper portions of the tabs and said lower edges being of substantially the same length as the bases of the recesses, certain of the tabs being positioned over the abutting ends of two elements in the course below to protect the joint formed by said ends.

2. Shingle elements assembled on a roof in overlapping courses, each course having alternating depending tabs and recesses, the recesses being complementary in shape to the tabs, and each course comprising a plurality of separate elements having end extensions which abut one another, the lower edges of said abutting end extensions forming the bases of some of the recesses, said tabs having their lower edges straight and of greater length than the upper portions of the tabs and said lower edges being of substantially the same length as the bases of the recesses, certain of the tabs being positioned over the abutting ends of two elements in the course beliw to protect the joint formed by said en s.

3. Shingle elements assembled on a roof in overlapping courses, each course having alternating depending tabs and recesses, the recesses being complementary in shape to the tabs, and each course comprising a plurality of separate elements having end extensions which abut one another, the lower edges of said abutting end extensions formin the bases of some of the recesses, said ta having their lower edges of greater length than the upper portions of the tabs and said lower edges being of substantially the same length as the bases of the recesses,

certain of the tabs being positioned over the abutting ends of two elements in the course below to protect the joint formed by said ends, the lower edges of the tabs substantially alining with the bases of the recesses.

'4. Shingle elements assembled on a roof in overlapping courses, each course having alternating depending tabs and recesses, the recesses being complementary in shape to the tabs and the latter having downwardly diverging sides, each course comprising a plurality of separate elements having end extensions which abut one another, the lower edges of said abutting end extensions forming the bases of some of the recesses and the lower edges of the tabs being of substantially the same length as the bases of the recesses, certain of the tabs being positioned over the abutting ends of two elements in the course below to protect the joint formed by said ends and the diverging sides of the tabs directing rain and the like away from said joint.

5. Shingle elements assembled on a roof in overlapping courses, each course having a1- ternating depending tabs and recesses, the recesses being complementary in shape to the tabs and each course comprising a plurality of separate elements having end extensions which abut one another, the lower edges of said abutting end extensions forming bases of some of the recesses, said tabs having a pair of straight downwardly diverging side edges and a straight bottom edge connecting said side edges to form a dovetail projection, the said bottom edge being of substantially the same length as the bases of the recesses, certain of the tabs being positioned over the abutting-ends of two elements in the course below to protect the joint formed by said ends, the diverging side edges directing rain away from the joint.

6. Shingle elements assembled on a roof in overlapped courses, each course having alternating depending tabs and recesses, the recesses being complementary in shape to the tabs, and each course comprising a plurality of separate elements having end extensions adjacent one another, the lower edges of said adjacent end extensions forming the bases of some of the recesses, said tabs having their lower edges of greater length than the upper portions of ing of substantially the same length as the bases of the recesses, certain of the tabs being positioned over the adjacent ends of two elements in the course below to protect the joint formed by said ends.

7. Shingle strips overlapping courses, rality of alternating depending tabs and recesses, the recesses being complementar in shape to the tabs, said strips having en extensions adjacent one another, the lower edges of said adjacent end extensions cooperating to formthe bases of some of the reassembled on a roof in the tabs and said lower edges beeach strip having a plu-' cesses between tabs in each course, said tabs havin their lower edges of greater length than t e upper portions of the tabs and said lower edges being of substantially the same length as the bases of the recesses, certain of the tabs being positioned over the adjacent ends of the two strips in the course below to protect the joint formed by said ends.

8. Shingle strips assembled. on a roof in overlapping courses, each strip having a plurality of alternating depending tabs and recesses, the recesses being complementary in shape to the tabs, and said strips having end extensions adjacent one another, the lower edges of said adjacent end extensions cooperating to form the bases of some of the recesses between tabs in each course, said tabs having their lower edges of greater length than the upper portions of the tabs, said lower edges wholly overlying the body por- 7 tion of the strips of a course below and being of substantially the same length as the bases of the recesses, certain of the tabs being positioned over the adjacent ends of the two strips in the course below to protect the joint 0 formed by said ends.
